TO ALL WHOM IT MAY CONCERN:

Be it known that I, EDWARD L. GILMAN, of Somerville, in the county of Middlesex, and in the State of Massachusetts, have invented certain new and useful Improvements in Churns; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification.

In the annexed drawings A represents the churn-box, which is oblong or any other suitable form, having a lid, A, through which the dasher-shafts are passed. This lid has a suitable frame, 13, secured upon it, upon which aretwo cog-wheels C C, with an idle-wheel, C, between them, and a small cog-wheel, C upon the front of the idle-wheel C. These wheels are connected to this frame so as to readily revolve. 13' represents hearings secured to each side of the lid A, through which is passed a horizontal shaft having 5. cog-wheel, D, so placed ,as to mesh into the small cog C and is also provided with a balance-wheel, b, with crank for revolving the wheels. Each of the wheels 0 has a pin on its face, to which are connected the pitmen E E. F F represent the dasher-shafts, which are secured to the lower ends of the pitmen, and pass through the cover, so as to project into the churn-box. Connected to the extremities of these shafts, a short distance from each other, as shown, are two dashers, G G. Said dashers are constructed somewhat in the form of two ordinary windowshutters, crossing each other at their centres. The slats :v x :v in these dashers are set at asuitahle angle, and the dashers placed upon the shafts so that the upper dasher-slots will be at opposite angles, allowing the cream to How inwards towards the dasher-shaft through the lower dasher-slats, and then outwards from the shaft through the upper dasher-slats. H represent two metallic perforated cups placed above and below the lid A, having a suitable opening and thimble for the dasher-shaft to pass through the centre. These cups are used for the purpose of guiding and keeping the shaft F in position, and by means of the perforations in the lid A allow the ingress of air on to the cream, andprevent the egress of the cream.

It will be seen that by turning the crank-wheel 12, motion is imparted through wheel D to wheel 0, wheel 0 and wheels C'C, thereby causing-the pitmen to work simultaneously up and down, causing the dasher-shaft to work the dashers and the cream.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The dashers G'Gr, constructed as described, and used with the shaft F, in the manner and for the purposes set forth.

2. The cups H H, perforated as described. and used upon the lid A, with the dasher-shaft F, in the manner specified.

3. The arrangement of the frame B upon the lid, with wheels C C 0 C pitmen E E, with their dashcrs' and shafts operated by the wheel D, in the manner and for the purposes described.

In testimony that I claim the foregoing I have hereunto set-my hand this 10th day of July, 1867.
